Fewer Mexicans immigrating to US

Yesterday's NYT reports that the wave of Mexican immigration to the US may have crested.  The incentives to immigrate depend on the difference between opportunities in the US and Mexico as well as the cost of making the move.  The cost has risen, thanks to increased border enforcement and the spread of gang activity along the border.  Opportunities in the US have stagnated, as we all know. 

The article highlights another critical factor that has not received much attention: increased opportunity for those who stay in Mexico.  Mexico has significantly upgraded its educational system, making high school and college more accessible.  Mexican fertility rates have fallen dramatically, close to US levels, cutting into what had been a perpetual excess supply of labor.  The article also notes that "democracy is better established, incomes have generally risen and poverty has declined."
